8 + 100 , 9 + 10 , 7 + 1
is that what you meant
Answer:
Step-by-step explanation:
So we have the equation:
First, let's distribute the left side of our equation:
Multiply:
Now, let's isolate the y-variable. Subtract 4y from both sides:
The right side cancels. Subtract on the left. So:
Now, subtract 5 from both sides:
The left side cancels. Subtract on the right:
Now, divide both sides by 6. So:
The left will cancel. Therefore:
And we're done!
Answer:
C
Step-by-step explanation:
The number of ribbon needs depends on the number of bows times 3 so
r= b x 3
Answer:
x = 5, y = -1/2
Step-by-step explanation:
3.5x - 5y = 20
3x + 4y = 13 multiply by 1.25 so the y's match up (you could match x's too)
3.75x + 5y = 16.25
–––––––––––––––––––––––
3.5x - 5y = 20
3.75x +5y = 16.25
7.25x + 0y = 36.25 you can add or subtract here (on this equation you add)
7.25x=36.25
x=5 So now we have x=5 and to find y we can just plug in x into one of the equations
–––––––––––––––––––
3(5) + 4y = 13
15 + 4y = 13
4y = -2
y = -1/2
x = 5, y = -1/2
Then you can plug in both to check your answers.
Answer:
probability is 1/6
Step-by-step explanation:
there are 6 sides of a die, so each side has a 1/6 chance of getting landed on. you put the amount of desired outcomes over the possibilities.
